A side of the guide via 330 is formed to be opened to a side of the holder body 310. As the side of the guide via 330 is opened at a side of the holder body 310, the knob 430 protruded from the connection pin portion 400 to be described below can be inserted into the guide via 330. The guide via 330 is formed to have a predetermined length in a direction of the other side from the opened side. Here, the “predetermined length” can be provided as a travelling distance of the knob that allows one of the first protrusion 421 or the second protrusion of the connection pin portion 400 to be described below as pulled out from the pin via 111.

The guide via 330 is positioned corresponding to the exposure via 220 and extends to the exposure via 220 to be opened to the outside of the strap portion 200. The guide via 330 can be similar in size to the exposure via 220; and the guide via 330 and the exposure via 220 form a travelling distance for the knob 430 of the connection pin portion 400. The knob 430 is inserted along the guide via 330 and is exposed to the outside of the back surface of the strap portion 200 through the guide via 330 and the exposure via 220. The user may move the knob 430 to slide the connection pin portion 400 into and from the body portion 100.

The knob 430 is able to be removed or fall out of the holder body 310 through the opened end of the guide via 330. To prevent such removal or extraction, or to restrict the movement of the knob 430, a pair of stopper portions 331 facing each other is provided in the guide via 330. The knob 430 is press-fittingly inserted into the guide via 330 through the opened end of the guide via 330 and the space between the stopper portions 331 and can be thus positioned between the opposite end of the opened end of the guide via 330 and the stopper portions 331, so that the knob 430 can travel between the opposite side of the guide via 330 and the stopper portions 331, with the connection pin portion 400 inserted in the pin mounted via 320.

The connection pin portion 400 differs in structure from the connection pin portion 400 described above in connection with FIGS. 1 to 4.

The connection pin portion 400, similar to that described above in connection with FIGS. 1 to 4, is inserted into the holder portion 300, specifically the pin mounted hole 320, to couple the strap portion 200 with the body portion 100. The connection pin portion 400 includes a pin body 410, first and second protrusions projecting from the pin body 410 and detachably inserted into the pin vias 111, and a knob that makes it distinct from the connection pin portion 400 described above in connection with FIGS. 1 to 4.

The holder portion 300 is positioned inside the strap portion 200, with the pin body 410 inserted in the holder portion 300. The pin body 410 is shaped as an arm penetrating the pin mounted via 320 from a side to the other side thereof, and the pin body 410 is provided to be inserted and engaged to the pin mounted via 320.

The first and second protrusions 421 and 422 are fitted into or removed from the pin vias 111 of the strap coupler portion sticking out on two opposite ends of the pin body 410. The first protrusion 421 or the second protrusion 422 is connected with the knob 430 and can be elastically supported by an elastic member 440, e.g., a spring. According to an embodiment of the present disclosure, the second protrusion 422 (hereinafter, referred to as a spring pin 422) is connected with the knob 430, for the purpose of description. However, the first protrusion 421 can be fitted into or removed from the inside of the pin body 410 as well. Alternatively, the first protrusion 421 can be a spring pin depending on the position of the guide via 330 and the exposure via 220. When the knob 430 is pulled away from the stopper portions 331, the spring pin 422 can be pushed in along the inside of the pin body 410, and thus, the connection pin portion 400 can be shrunken, subject to the position where the connection pin portion 400 can be unplugged from the pin vias 111 or fitted back into the pin via 111.

An example of swapping straps is now described with reference to FIG. 11, according to an embodiment of the present disclosure.

To swap strap portions 200, the user pulls the knob 430, sticking out through the exposure hole 220 on the back surface of the strap portion 200, from a side to another (in the direction indicated by an arrow) (see FIG. 11(a)-1). The knob 430 runs along the guide via 330, but not beyond the stopper portions 331, preventing damage to the strap portion 200, specifically the engagement part, which otherwise might occur. As the knob 430 moves along, the spring pin 422 connected with the knob 430 can be pushed inside the pin body 410. The spring pin 422 is pulled away from the pin hole 111, allowing the side of the strap portion 200 to be separated from the body portion 100 (see FIG. 11(b)).

The following is an exemplary operation of reinstalling the strap portion 200 to the body portion 100 (refer to FIG. 11(c) to (e)).

The holder portion 300 having the connection pin portion 400 inserted therein remains fastened in the seating opening 210. The first protrusion 421 and the spring fin 422 of the connection pin portion 400 are left sticking out from both sides of the strap portion 200. The first protrusion 421 is fitted into the pin via 111 (see FIGS. 11(c) and (c)-1). The knob 430 projected through the exposure via 220 on the back surface of the strap portion 200 is pulled away from the stopper portions 331 (in the direction indicated by an arrow) (see FIG. 11(d)-1), the spring pin 422 is forced into the inside of the pin body 410 (see FIGS. 11(e) and (e)-1). The knob 430 travels along the guide via 330, but not beyond the stopper portions 331, preventing damage that otherwise might arise. As the spring pin 422 is pushed inside of the pin body 410, the strap portion 200 can be fitted into the strap coupler portion 110. When the knob 430 is released, the knob 430 along with the spring pin 422 is elastically pushed towards the stopper portions 331 by the elastic member 440, leaving the spring pin 422 to spring out of the side of the pin body 410 to fit into the pin via 111 of the strap coupler portion 110. As such, the strap portion 200 can be easily coupled with the body portion 110.
